Red Lightsaber

The Red Lightsaber shows darkness, it also represents aggression and fear, fear to those who dare cross the Sith. It is described among others to be most powerful, in fact the Red Lightsaber can destroy an opponent's Lightsaber. This is because it is not made with a regular Kyber crystal from Ilum but made from artificial crystals created by Sith. There have not been any known Jedi to appear with a Red Lightsaber, however Adi Galia once had one before her blue one but there's no true evidence that this is canon. There were many common users having Red Lightsabers but the most common were: Darth Vader(Sith), Darth Sidious, Darth Maul, Darth Tyranus (Count Dooku, Sith), Kylo Ren, Savage Opress, Inquisitor etc, that used the dark side feelings such as anger to destroy others.
